Definitions

  • the present invention relates to bicycle brakes, and more particularly to a structure for connecting a brake control cable to a brake caliper having a brake pad.
  • a conventional bicycle brake includes a pair of brake calipers having brake pads and pivotably attached to a bicycle frame.
  • the brake calipers are connected through a connecting mechanism to a brake control cable operable by a brake lever.
  • the connecting mechanism is adjustable to determine a position of the control cable relative to the brake calipers, thereby to adjust positions of the brake calipers relative to a wheel.
  • one of the brake calipers includes a cable clamping screw having an axis extending parallel to a pivotal axis of this caliper.
  • the caliper With the axis of the cable clamping screw extending parallel to the pivotal axis of the brake caliper, the caliper also tends to pivot under a force applied to turn and tighten the clamping screw in adjusting the position of the control cable. It is therefore necessary to turn the brake caliper when adjusting the cable clamping screw.
  • US-A-5 058 450 discloses a bicycle brake apparatus having the features of the preamble of claim 1.
  • An object of the present invention is to provide a brake control cable connecting mechanism for allowing positional adjustment of a control cable relative to a brake caliper without turning the caliper.
  • Another object of the invention is to provide a brake control cable connecting mechanism for facilitating positional adjustment of a control cable by allowing an adjusting operation to be carried out at an upper outward position of a bicycle.
  • Each brake caliper includes a proximal region pivotally attached to the bicycle frame, a brake pad mounting region for supporting a brake pad, and an arm region extending from the brake pad mounting region.
  • the connecting device includes a control cable receiving surface formed on the arm region of one of the brake calipers, and a cable clamp for engaging the control cable receiving surface.
  • the cable clamp is movable along a second axis extending substantially parallel to the arm region of this brake caliper to fixedly hold the brake control cable between the control cable receiving surface and the cable clamp.
  • the second axis extends substantially perpendicular to the first axis and in a direction outwardly and upwardly of the bicycle.
  • the axis of the wire clamp is perpendicular to the axis about which one of the brake calipers is pivotable. This allows the control cable to be positionally adjusted relative to the brake caliper without turning the latter.
  • the axis of the wire clamp extends outwardly and upwardly of the bicycle, access may be made to the wire clamp with ease to facilitate positional adjustment of the brake caliper.
  • Fig. 1 shows a cantilever type caliper brake of a bicycle.
  • This brake includes a pair of brake calipers 1 attached to a bicycle frame 7.
  • Each of the brake calipers 1 is pivotable relative to the frame 7 about an axis X.
  • Each brake caliper 1 has a spring case 2 in a proximal portion thereof, and a mounting element 3 in an intermediate portion for supporting a brake pad 4.
  • One of the brake calipers 1 includes a clamping screw 5 for connecting a brake control cable 8 thereto.
  • the other brake caliper 1 includes a stopper 6c for securing a connecting cable 6 thereto.
  • each brake caliper 1 has a portion from the spring case 2 to the mounting element 3 extending substantially parallel to the frame 7, and a portion from the mounting element 3 to the clamping screw 5 or stopper 6c extending outwardly and upwardly of the bicycle.
  • the spring case 2 is attached to a brake bracket 9 formed on the frame 7.
  • the bracket 9 includes a support shaft 9a, and the spring case 2 is rotatably attached to the support shaft 9a by a screw 11.
  • the spring case 2 contains a coil type return spring 10.
  • the return spring 10 has one end thereof fitted in a mounting hole 2a defined in the spring case 2, and the other end fitted in a mounting hole 9b defined in the bracket 9.
  • the brake caliper 1 is biased by the return spring 10 to a non-braking position (OFF) as shown in Fig. 3.
  • the brake control cable 8 extends through a cable joint 6a to he connected to one of the brake calipers 1 by the cable clamping screw 5.
  • the cable joint 6a is connected to the other brake caliper 1 through the connecting cable 6 having cable stoppers 6b and 6c.
  • the control cable 8 is operable by a brake lever (not shown) to cause each brake caliper 1 to pivot about the axis X from the non-braking position OFF to a braking position ON shown in Fig. 3. This moves the brake pad 4 into contact with a rim 12 of a wheel W.
  • each brake caliper 1 Upon relaxation of the control cable 8, each brake caliper 1 returns to the non-braking position OFF under the biasing force of the return spring 10.
  • the cable clamping screw 5 has an axis Y, and is meshed with a free end of the brake caliper 1.
  • the axis Y extends substantially perpendicular to the axis X.
  • the clamping screw 5 has a head defining a hexagon socket 5a for receiving a spanner, and a clamping surface 5b for clamping the control cable 8.
  • the clamping surface 5b may be formed of metal or a hard elastic material such as plastic.
  • the surface 5b may be a flat surface or an undulating surface.
  • the clamping screw 5 is tightened with the control cable 8 held between the clamping screw 5 and a linear groove 1a formed in the brake caliper 1, thereby fixing the control cable 8 to the brake caliper 1.
  • the cable clamping screw 5 may have a hexagonal head to be tightened with a spanner, instead of the head defining the socket 5a.
  • each brake caliper 1 extends substantially straight upward from the axis X to the mounting element 3, and from the mounting element 3 outwardly and upwardly of the frame 7. Consequently, the clamping screw 5 has the axis Y extending in a direction to allow easy access when positionally adjusting the control cable 8 relative to the brake caliper 1.
  • an extension line from the axis Y passes through a position between the axis X and rim 12.
  • the clamping screw 5 may be tightened while pushing the screw 5 with a spanner along the axis Y against the biasing force acting to move the brake caliper 1 away from the rim 12.
  • the caliper 1 Since the axis Y of the clamping screw 5 extends substantially perpendicular to the axis of the brake caliper 1, the caliper 1 does not turn while the clamping screw 5 is turned for adjustment. This facilitates positional adjustment of the control cable 8 relative to the brake caliper 1.
